Definitions
- the present invention relates to a scaffolding structure, in particular facade scaffolding.
- a facade scaffolding comprises a structure formed of vertical elements, especially in the form of prefabricated or non-prefabricated superposed frames, with uprights and crosspieces, which are interconnected by floors at different levels, and also by permanent guardrails which provide protection against falls, at least on the outside of the scaffolding (supposedly installed in front of a building facade or other building).
- guardrails designed for such a secure mounting have either end uprights extended downward or hinge fastening systems, facilitating their handling and attachment to the upper floor level, since the lower floor level, possibly by rotating the railing around an attachment point.
- the present invention aims to avoid this drawback, and its main purpose, in addition to the use of railings that can be mounted from a lower floor level, to make mandatory the implementation in place of such a railing, before mounting the floor of the upper level (and not the other way around).
- the subject of the invention is a scaffolding structure, in particular a façade scaffold, formed of vertical elements, in particular in the form of prefabricated or non-prefabricated frames, with uprights and crosspieces, which are interconnected.
- a scaffolding structure in particular a façade scaffold, formed of vertical elements, in particular in the form of prefabricated or non-prefabricated frames, with uprights and crosspieces, which are interconnected.
- these railings being designed to be mounted from the floor level immediately below the floor level to be protected
- this structure of scaffolding being essentially characterized by the fact that the permanent guardrails comprise, in their lower part, at least one element directed inwards, with reference to the mounted position of the railing, this element taking place at the height of the floor of the level to be protected, so that if this floor is already in place the guardrail can no longer be installed, and said element near forming a recessed conformation to normally receive the longitudinal edge of the corresponding floor.
- each guardrail there is provided on each guardrail an element which, if the floor is already installed at the level considered, forms a stop holding the railing away from its final mounting position, thus preventing the engagement fasteners of this railing in the complementary parts provided on the uprights of the scaffolding structure.
- the or each element directed inwards, provided in the lower part of the railings is a "U" profile piece, the two branches of which are directed upwards. so as to normally receive between them a longitudinal profile bordering the corresponding floor.
- the edge profile of the floor will take place “naturally” in the "U” profile piece, during the subsequent assembly of the floor.
- the "U" profile piece will abut by its inner limb against an outer face of the longitudinal profile of the floor, thus preventing the installation of the guardrail. .
- the element such as a "U" profile piece is provided in the region of at least one of the two lower fasteners of the railing, and therefore towards one end of the guardrail.
- This element may in particular be screwed or welded to a lower fastener of the railing, in particular on the bracket of the fastener in the case of a stirrup and key fastener. This caliper is thus used for an additional function.
- the element such as "U" profile piece may also be provided at an intermediate point of the length of the railing, as long as this element can be rigidly attached to a part of this railing.
- the invention also relates to a permanent scaffolding railing designed to be mounted from the floor level immediately below the floor level to be protected, this railing intended for a scaffolding structure as previously defined comprising, in its lower part, at least one element directed inwardly of this railing and intended to abut against the edge of a floor if the latter is installed before the railing, said element having a recessed configuration for normally receive the longitudinal edge of the corresponding floor.
- the invention relates to a scaffolding whose structure comprises vertical elements 1, in the form of frames 2 superimposed, prefabricated or not, composed of vertical uprights 3 and cross members 4 horizontally connecting the uprights 3.
- the vertical elements 1 and formed, spaced apart from each other in the longitudinal direction of the scaffold, are connected to each other by floors 5 at different levels, the floors 5 being hooked at their ends to the cross members 4 by means known per se.
- At each floor level is placed at least one permanent guardrail placed on the outside of the scaffold (used as a facade scaffolding).
- the protection provided by the railing 6 can be completed by a baseboard 7, located at the edge of the floor 5 in the longitudinal direction.
- the configuration of the railing 6 is adapted for its safe assembly from the floor level located immediately below the level to be protected, and also adapted for the implementation of the baseboard 7.
- the railing 6 comprises an upper rail 8 and a sub-rail 9, joined in a one-piece structure by two end uprights 10 and 11, which extend downward below the sub-rail 9.
- the structure of the guard -body 6 further comprises two oblique elements 12 and 13 of bracing. These oblique elements 12 and 13 respectively depart from the lower part of the two end uprights 10 and 11; they converge towards a plate 14 connected to the median zone of the upper rail 8. All the constituent elements of the railing 6, described so far, are located substantially in the same vertical plane, designated as "railing plan" .
- the two ends of the railing 6 are provided with fasteners designed for fastening this railing 6 to the structure of the scaffolding, the uprights 3 are provided, at different levels, sockets 15 vertical axis adapted to receive said fasteners.
- These fasteners comprise, at the top of each of the two end posts 10 and 11 of the guardrail, respective hooks 16 and 17 directed downwards - see in particular the Figures 2 and 4 .
- the hooks 16 and 17 are not located in the plane of the guardrail, but they are located in respective vertical planes which form an acute angle, for example about 45 °, with the plane of the guardrail.
- the fasteners also comprise, at the base of the two end uprights 10 and 11 of the guardrail 6, stirrups 18 traversed vertically by movable keys 19, in particular -see in particular the figure 7 .
- the stirrups 18 each have a vertical median plane which forms an acute angle, for example about 45 °, with the plane of the guardrail.
- the four fasteners of the guardrail 6, namely the two hooks 16 and 17 and the two stirrups 18 with their keys 19, are thus oriented towards the same side of the plane of the guardrail, namely the inner side.
- the guardrail 6 is equipped in its lower part with a "U" profile element 20 which is also directed towards the inner side of this railing 6.
- the element 20 is a piece reported metal which has two branches directed upwards 21 and 22, connected by a horizontal portion 23 located at their base.
- One of the branches 21 directed upwards, oriented vertically is fixed for example by welding or screwing, at a lower attachment (bracket 18) of the railing 6.
- the other branch 22, which is free, is here an oblique branch deviating from the first branch 21.
- the drawing illustrates the successive steps of mounting the railing 6 and the corresponding floor 5, mounting that is performed from the floor level immediately below.
- the operator straightens the railing 6, and he positions the hook 17 of the other end of the railing 6 in a socket 15 located at same level, but on another amount 3.
- the guardrail 6 is straightened horizontally, and its other upper fastener, in other words the other hook 17, is inserted into the sleeve 15 corresponding (see Figures 3 and 4 , as well as figure 6 ).
- one of the lower caliper fasteners 18 is engaged on either side of a bushing 15 located at the same level, and the key 19 is depressed and locked to secure the stirrup 18 with the bushing 15. (see Figures 5 and 7 ).
- the guardrail 6 is then fixed, by its four fasteners, on the structure of the scaffolding. More particularly, given the orientation of its fasteners, the guardrail 6 is thus positioned so that its vertical plane is located outside the plane of the uprights 3 of the scaffolding structure, thus completely releasing the space between these amounts 3.
- the floor 5 of the level corresponding to the railing 6 can be brought and hooked to the cross members 4 of the scaffolding structure (see figure 8 ).
- a plinth 7 is provided, it is placed in the free space formed between the uprights 3, by the offset to the outside of the plane of the guardrail 6.
- the same procedure is followed for all additional floor levels, each time requiring the guardrail 6 to be raised before the floor 5.
- the planned configuration requires to dismount each floor 5 before removing the railing 6 of the same level, and not the opposite, so that no floor 5 can remain in place without protection.
- the figure 11 illustrates a first variant, relating to the shape of the element 20.
- This again has a profile in the general form of "U”, but with two branches 21 and 22 of very unequal heights, connected at their base by a part 23 slightly sloping on the horizontal.
- the branch 22 is here again oblique, but it approaches the first branch 21 instead of departing from it.
- the figure 12 illustrates a second variant, also relating to the shape of the element 20. This again has a profile in the general shape of "U”, but rounded and not angular, especially in its part passing under the profile 24 from the edge of the floor 5.
- the element 20 has a recessed configuration, to normally receive the profile 24 which forms the longitudinal edge of the floor 5, while prohibiting the assembly of the railing 6 after the establishment of the floor 5.
- skirting 7 is here constituted by a profile carried by the longitudinal edge of the guardrail 6, but skirting of other shape, or differently fixed for example directly to the uprights 3, are also conceivable.

Abstract
Description
La présente invention concerne une structure d'échafaudage, en particulier d'échafaudage de façade.The present invention relates to a scaffolding structure, in particular facade scaffolding.
D'une manière généralement connue, un échafaudage de façade comprend une structure formée d'éléments verticaux notamment sous la forme de cadres superposés préfabriqués ou non, avec montants et traverses, qui sont reliés entre eux par des planchers situés à différents niveaux, et aussi par des garde-corps permanents qui assurent la protection contre les chutes, au moins sur le côté extérieur de l'échafaudage (supposé installé devant une façade d'immeuble ou autre bâtiment).In a generally known manner, a facade scaffolding comprises a structure formed of vertical elements, especially in the form of prefabricated or non-prefabricated superposed frames, with uprights and crosspieces, which are interconnected by floors at different levels, and also by permanent guardrails which provide protection against falls, at least on the outside of the scaffolding (supposedly installed in front of a building facade or other building).
Pour réaliser un montage en sécurité d'un tel échafaudage, les garde-corps permanents de conception récente sont agencés de manière à pouvoir être mis en place à partir d'un niveau de plancher, pour le niveau de plancher immédiatement supérieur. Ce principe permet aux opérateurs d'accéder à un niveau de plancher supérieur en toute sécurité puisque les garde-corps de ce niveau supérieur sont alors déjà installés, depuis le niveau immédiatement inférieur qui était lui-même déjà protégé, et ainsi de suite... D'une manière générale, les garde-corps conçus pour un tel montage en sécurité possèdent soit des montants terminaux prolongés vers le bas, soit des systèmes d'attache avec articulation, facilitant leur manipulation et leur accrochage au niveau de plancher supérieur, depuis le niveau de plancher inférieur, éventuellement en faisant pivoter le garde-corps autour d'un point d'attache. A titre d'exemples de tels garde-corps permanents à montage en sécurité, il est ici fait référence aux brevets français
Toutefois, même si les garde-corps actuels sont conçus pour un montage depuis le niveau de plancher inférieur, rien n'oblige les monteurs à effectuer une telle opération, donc à sécuriser le niveau supérieur avant d'accéder à ce niveau, de manière à éviter les risques d'accidents. Autrement dit, il reste possible à un opérateur de monter d'abord le plancher du niveau supérieur, puis d'accéder à ce plancher sans être sécurisé et de n'installer qu'ensuite, depuis le plancher du niveau supérieur, le garde-corps destiné à la protection de ce niveau de plancher. Une telle situation n'est certainement pas satisfaisante, du point de vue de la sécurité.However, even if the current guardrails are designed for mounting from the lower floor level, there is no requirement for the assemblers to perform such an operation, so to secure the upper level before accessing this level, so that avoid the risk of accidents. In other words, it remains possible for an operator to first mount the floor of the upper level, then access this floor without being secure and then install, from the floor of the upper level, the guardrail intended for the protection of this floor level. Such a situation is certainly not satisfactory from the point of view of security.
La présente invention vise à éviter cet inconvénient, et elle a donc pour principal objectif, en complément de l'utilisation de garde-corps pouvant être montés depuis un niveau de plancher inférieur, à rendre obligatoire la mise en place d'un tel garde-corps, avant le montage du plancher du niveau supérieur (et non pas l'inverse).The present invention aims to avoid this drawback, and its main purpose, in addition to the use of railings that can be mounted from a lower floor level, to make mandatory the implementation in place of such a railing, before mounting the floor of the upper level (and not the other way around).
A cet effet, l'invention a pour objet une structure d'échafaudage, en particulier d'échafaudage de façade, formée d'éléments verticaux notamment sous la forme de cadres superposés préfabriqués ou non, avec montants et traverses, qui sont reliés entre eux par des planchers situés à différents niveaux, et aussi par des garde-corps permanents prévus aux différents niveaux de planchers, ces garde-corps étant conçus pour être montés depuis le niveau de plancher immédiatement inférieur au niveau de plancher à protéger, cette structure d'échafaudage étant essentiellement caractérisée par le fait que les garde-corps permanents comportent, dans leur partie inférieure, au moins un élément dirigé vers l'intérieur, par référence à la position montée du garde-corps, cet élément prenant place à hauteur du plancher du niveau à protéger, de telle sorte que si ce plancher est déjà en place le garde-corps ne puisse plus être installé, et ledit élément présentant une conformation évidée pour normalement recevoir la bordure longitudinale du plancher correspondant.For this purpose, the subject of the invention is a scaffolding structure, in particular a façade scaffold, formed of vertical elements, in particular in the form of prefabricated or non-prefabricated frames, with uprights and crosspieces, which are interconnected. by floors at different levels, and also by permanent guardrails provided at different levels of floors, these railings being designed to be mounted from the floor level immediately below the floor level to be protected, this structure of scaffolding being essentially characterized by the fact that the permanent guardrails comprise, in their lower part, at least one element directed inwards, with reference to the mounted position of the railing, this element taking place at the height of the floor of the level to be protected, so that if this floor is already in place the guardrail can no longer be installed, and said element near forming a recessed conformation to normally receive the longitudinal edge of the corresponding floor.
En d'autres termes, il est prévu sur chaque garde-corps un élément qui, si le plancher est déjà installé au niveau considéré, forme une butée maintenant le garde-corps à distance de sa position finale de montage, donc empêchant l'engagement des attaches de ce garde-corps dans les parties complémentaires prévues sur les montants de la structure d'échafaudage. Ceci contraint les monteurs à procéder de manière sécurisée, c'est-à-dire à sécuriser le niveau de plancher immédiatement supérieur en y installant le garde-corps, avant d'amener le plancher lui-même dont la bordure s'imbriquera alors dans ledit élément.In other words, there is provided on each guardrail an element which, if the floor is already installed at the level considered, forms a stop holding the railing away from its final mounting position, thus preventing the engagement fasteners of this railing in the complementary parts provided on the uprights of the scaffolding structure. This forces the assemblers to proceed in a secure manner, that is to say to secure the next higher floor level by installing the railing, before bringing the floor itself whose edge will then fit into said element.
Dans une forme de réalisation préférée de l'invention, le ou chaque élément dirigé vers l'intérieur, prévu dans la partie inférieure des garde-corps, est une pièce de profil en « U », dont les deux branches sont dirigées vers le haut de manière à normalement recevoir entre elles un profilé longitudinal bordant le plancher correspondant. Comme on le comprend, si le garde-corps est préalablement installé, le profilé de bordure du plancher va prendre place « naturellement » dans la pièce de profil en « U », lors du montage ultérieur du plancher. A l'inverse, si le plancher est installé avant le garde-corps, la pièce de profil en « U » va buter par sa branche intérieure contre une face extérieure du profilé longitudinal du plancher, empêchant ainsi la mise en place du garde-corps.In a preferred embodiment of the invention, the or each element directed inwards, provided in the lower part of the railings, is a "U" profile piece, the two branches of which are directed upwards. so as to normally receive between them a longitudinal profile bordering the corresponding floor. As it is understood, if the guardrail is previously installed, the edge profile of the floor will take place "naturally" in the "U" profile piece, during the subsequent assembly of the floor. Conversely, if the floor is installed before the guardrail, the "U" profile piece will abut by its inner limb against an outer face of the longitudinal profile of the floor, thus preventing the installation of the guardrail. .
Avantageusement, l'élément tel que pièce de profil en « U » est prévu dans la région de l'une au moins des deux attaches inférieures du garde-corps, donc vers une extrémité du garde-corps. Cet élément peut notamment être vissé ou soudé sur une attache inférieure du garde-corps, en particulier sur l'étrier de l'attache dans le cas d'une attache à étrier et à clavette. Cet étrier est ainsi mis à profit pour une fonction supplémentaire.Advantageously, the element such as a "U" profile piece is provided in the region of at least one of the two lower fasteners of the railing, and therefore towards one end of the guardrail. This element may in particular be screwed or welded to a lower fastener of the railing, in particular on the bracket of the fastener in the case of a stirrup and key fastener. This caliper is thus used for an additional function.
En variante, l'élément tel que pièce de profil en « U » peut aussi être prévu en un point intermédiaire de la longueur du garde-corps, du moment que cet élément puisse être rigidement fixé à une partie de ce garde-corps.Alternatively, the element such as "U" profile piece may also be provided at an intermediate point of the length of the railing, as long as this element can be rigidly attached to a part of this railing.
L'invention a aussi pour objet un garde-corps permanent d'écahfaudage conçu pour être monté depuis le niveau de plancher immédiatement inférieur au niveau de plancher à protéger, ce garde-corps destiné à une structure d'échafaudage telle que précédemment définie comportant, dans sa partie inférieure, au moins un élément dirigé vers l'intérieur de ce garde-corps et prévu pour venir en butée contre la bordure d'un plancher si ce dernier est installé avant le garde-corps, ledit élément présentant une conformation évidée pour normalement recevoir la bordure longitudinale du plancher correspondant.The invention also relates to a permanent scaffolding railing designed to be mounted from the floor level immediately below the floor level to be protected, this railing intended for a scaffolding structure as previously defined comprising, in its lower part, at least one element directed inwardly of this railing and intended to abut against the edge of a floor if the latter is installed before the railing, said element having a recessed configuration for normally receive the longitudinal edge of the corresponding floor.

Comme le montre notamment la
La configuration du garde-corps 6 est adaptée pour son montage en sécurité à partir du niveau de plancher situé immédiatement au-dessous du niveau à protéger, et aussi adaptée pour la mise en place de la plinthe 7.The configuration of the
Le garde-corps 6 comprend une lisse supérieure 8 et une sous-lisse 9, réunies en une structure monobloc par deux montants terminaux 10 et 11, qui se prolongent vers le bas au-dessous de la sous-lisse 9. La structure du garde-corps 6 comprend encore deux éléments obliques 12 et 13 de contreventement. Ces éléments obliques 12 et 13 partent respectivement de la partie inférieure des deux montants terminaux 10 et 11; ils convergent vers une plaque 14 raccordée à la zone médiane de la lisse supérieure 8. Tous les éléments constitutifs du garde-corps 6, décrits jusqu'ici, sont situés sensiblement dans un même plan vertical, désigné comme « plan du garde-corps ».The
Les deux extrémités du garde-corps 6 sont pourvues d'attaches conçues pour la fixation de ce garde-corps 6 à la structure de l'échafaudage, dont les montants 3 sont pourvus, à différents niveaux, de douilles 15 d'axe vertical aptes à recevoir lesdites attaches.The two ends of the
Ces attaches comprennent, au sommet de chacun des deux montants terminaux 10 et 11 du garde-corps, des crochets respectifs 16 et 17 dirigés vers le bas -voir en particulier les
Les attaches comprennent encore, à la base des deux montants terminaux 10 et 11 du garde-corps 6, des étriers 18 traversés verticalement par des clavettes mobiles 19 respectives -voir en particulier la
Les quatre attaches du garde-corps 6, à savoir les deux crochets 16 et 17 et les deux étriers 18 avec leurs clavettes 19, sont ainsi orientés vers le même côté du plan du garde-corps, à savoir le coté intérieur.The four fasteners of the

L'une des branches 21 dirigées vers le haut, orientée verticalement est fixée par exemple par soudage ou vissage, au niveau d'une attache inférieure (étrier 18) du garde-corps 6. L'autre branche 22, qui est libre, est ici une branche oblique s'écartant de la première branche 21.One of the

L'opérateur (non représenté) posté sur le plancher 5 de ce niveau inférieur saisit d'abord le garde-corps 6 et le fait pivoter « en l'air » (voir
Ensuite, l'opérateur redresse le garde-corps 6, et il positionne le crochet 17 de l'autre extrémité du garde-corps 6 dans une douille 15 située au même niveau, mais sur un autre montant 3. A la fin de l'opération, le garde-corps 6 est redressé à l'horizontale, et son autre attache supérieure, autrement dit l'autre crochet 17, est introduite dans la douille 15 correspondante (voir
Dans une troisième étape, l'une des attaches inférieures à étrier 18 est engagée de part et d'autre d'une douille 15 située au même niveau, et la clavette 19 est enfoncée et bloquée pour solidariser l'étrier 18 avec la douille 15 (voir
Enfin, la même opération est répétée à l'autre extrémité du garde-corps 6, c'est-à-dire que l'autre étrier 18 est engagé sur la douille 15 située au même niveau mais sur l'autre montant 3, puis bloqué par enfoncement de la clavette 19 correspondante.Finally, the same operation is repeated at the other end of the
Le garde-corps 6 se trouve alors fixé, par ses quatre attaches, sur la structure de l'échafaudage. Plus particulièrement, compte tenu de l'orientation de ses attaches, le garde-corps 6 est ainsi positionné de telle sorte que son plan vertical se situe à l'extérieur du plan des montants 3 de la structure d'échafaudage, libérant ainsi totalement l'espace situé entre ces montants 3.The
Une fois le garde-corps 6 monté, de la manière qui vient d'être décrite, le plancher 5 du niveau correspondant à ce garde-corps 6 peut être amené et accroché aux traverses 4 de la structure d'échafaudage (voir
Ce plancher 5 étant ainsi monté après mise en place préalable du garde-corps 6, donc à un niveau déjà sécurisé, la présence de l'élément 20 de profil en « U » rend impossible un mode opératoire inverse, qui consisterait à monter d'abord le plancher 5 et ensuite seulement le garde-corps 6. En effet, comme le montre la
Enfin, si une plinthe 7 est prévue, celle-ci est mise en place dans l'espace libre ménagé, entre les montants 3, par le déport vers l'extérieur du plan du garde-corps 6.Finally, if a
Si l'échafaudage doit être rehaussé, il est procédé de la même manière pour tous les niveaux de planchers supplémentaires, avec obligation à chaque fois de monter le garde-corps 6 avant le plancher 5. Bien entendu, lors du démontage de l'échafaudage selon un processus inverse, la configuration prévue oblige à démonter chaque plancher 5 avant de retirer le garde-corps 6 du même niveau, et non l'inverse, de sorte qu'aucun plancher 5 ne peut rester en place sans protection.If the scaffolding is to be raised, the same procedure is followed for all additional floor levels, each time requiring the

Dans tous les cas, l'élément 20 présente une conformation évidée, pour normalement recevoir le profilé 24 qui forme la bordure longitudinale du plancher 5, tout en interdisant le montage du garde-corps 6 après la mise en place du plancher 5.In all cases, the
